This double core barrel gives a high penetration because of the small cutting surface. The inner non rotating tube preserves the sample from the torsional stress of the rods and prevents from washing out the core. It gives a high penetration in hard rocks because of the small cutting surface with all the consequent benefits as high coring percentage, less bending and wear on the equipment.
